Illustrate in this manual of the present invention preferably but in the application of non-exclusive, automatically reclose and close lock more precisely a kind of spring bolt electricity piston.

The structure of lock eliminates at press-in piston 5 and/or spring bolt 3 damages or in accidental activation situation, automatically locking of spring bolt 3.More particularly, the operation of this conjunction lock of automatically reclosing is as described below.

Door is opened.Second flexible member 6 applies elasticity and extracts power out on press-in piston 5, by the effect that press-in piston 5 engages with the second feeler wire part 10, this elasticity extracts the rotation torque that is dominant to distributor 8 transmission of power out, namely this be dominant rotation torque for by the first device 9 by being dominant with the conjugation of spring bolt 3 and the rotation torque extracting power out due to the elasticity be applied on spring bolt 3 by means of the first flexible member 4 and be delivered to distributor 8.

Therefore flexible member 4 maintains following kinematic chain, this kinematic chain is included in control lever 7, distributor 8 and spring bolt 3 in following configuration, limited withdrawn position and the reclining position of feeler wire part 10 on the second supporting zone 16 being pressed into piston 5 of this configuration and spring bolt 3 are corresponding, and this reclining position is maintained by the flexible member 6 in withdrawn position.

From this state, spring bolt and press-in piston 5 retract stroke during, all can not cause automatically locking of spring bolt 3 at any time.

In fact, feeler wire part 10 all can be caused to discharge from cam 65 in the actuating that is any unexpected or that have a mind to of retraction direction upper spring door bolt 3, thus spring bolt 3 be no longer connected by distributor 8 and can not interfere with press-in piston 5, thus causing being locked to each other.

Accident or the differential retraction having a mind to cause also can not trigger the locking of latch lock 3.

The rotation of the distributor 8 in fact caused by the retraction of spring bolt 3, as mentioned above, feeler wire part 10 can be advantageously caused to remove from the sidewall 11 of press-in piston 5, make after the accident on spring bolt 3 or the retraction force of having a mind to terminate, spring bolt 3 and press-in piston 5 can be taken back its original state automatically, namely, spring bolt 3 is got back to limited withdrawn position and is pressed into piston 5 and gets back to withdrawn position.

On the other hand, if be only pressed into piston 5 to be subject to outside retraction force, advantageously, when acting on the described outside retraction force on press-in piston 5 and being released, the kinematic chain comprising press-in piston 5, distributor 8 and spring bolt 3 performs auto-reverse motion.

Therefore, if press-in piston 5 and/or spring bolt 3 simultaneously or one of them be subject to external thrust, when described external thrust is released, the kinematic chain comprising press-in piston 5, distributor 8 and spring bolt 3 performs auto-reverse motion.

In order to close door, lock rests on door jamb and when the header board 23 of casing 2 contacts the opposed plate of door jamb, spring bolt 3 and press-in piston 5 start to bounce back simultaneously.Because press-in piston 5 applies pressure in whole parts of opposed plate, so before the header board 23 of casing 2 is aimed at completely with the opposed plate of door jamb, the retraction of press-in piston 5 continues always, but due to the effect of flexible member 4, spring bolt 3 can be made again to extract out and in opposed plate, find empty space.

Therefore, the extraction stroke of spring bolt 3 occurs, and press-in piston 5 is in advanced position, and what this advanced position was suitable for making presenting to feeler wire part 10 is no longer the second supporting zone 16 but the first supporting zone 15,50.

Therefore above-mentioned kinematic chain activated by flexible member 4, this flexible member causes distributor 8 to rotate, this rotation can not stop in the initial Angle Position adopted, this Angle Position is limited by the dependence of feeler wire part 10 on the second supporting zone 16, but this rotation can continue to carry out always until feeler wire part 10 is positioned at the first supporting zone 15,50 place.Therefore spring bolt 3 performs expansion withdrawn position, and this position is corresponding with the first device 9 of distributor 8 and the joint of cam 14.In this position, spring bolt 3 is locked, and radially discharges on the swinging axle 29 of distributor 8 this is because act axially on the retraction force on spring bolt 3, and not used for the component of rotary distributor 8.

Unlock and managed by electron plate 45, as requested, the bar 34 of this electron plate 45 active roll 30, corresponding the thin end of the scroll 34 overcomes the effect of flexible member 4 and activates aforementioned movement chain.

Lock is closed reliable especially according to automatic reclosing according to the present invention, safe and firm, and also its special tectonic can be applicable to the distance of the various possible center to center between lock boxboard plate opposed with door jamb flexibly.

Automatic reclosing as conceived herein is closed lock and is easy to amendment and distortion, and all these is within the scope of the present invention's design; In addition, all details can be substituted by the element be technically equal to.

The material used and size, in practice, can be as requested with any type of state of the art.
